This study aimed to compare the performance and safety profiles of two supraglottic airway devices (SADs), the Blockbuster laryngeal mask airway (LMA) and the Baska Mask (BM), in patients underwent laparoscopic cholecystectomy (LC).

Laparoscopic surgery has become increasingly prevalent across numerous surgical disciplines due to the well-established benefits it offers over traditional open procedures. Laparoscopic cholecystectomy (LC), the surgical removal of the gallbladder, stands out as one of the most frequently performed laparoscopic operations worldwide.

Supraglottic airway devices (SADs) play a crucial role in airway management algorithms, serving as viable alternatives in both anticipated and unanticipated difficult airway situations.

The laryngeal mask airway (LMA) can be utilized to establish a routine airway during general anesthesia or, less frequently, as a conduit for tracheal intubation. Newer, improved LMA designs incorporate cuffs that provide higher sealing pressures than classic LMAs, while also allowing for the venting of gastric contents through a dedicated drain tube.

The Baska Mask (BM), a second-generation SAD, features a non-inflatable cuff that is continuous with the airway channel, thereby inflating with positive pressure ventilation to improve cuff seal.

Inclusion Criteria:

• Aged 18-60 years
• Both sexes.
• American Society of Anesthesiologists (ASA) physical status I-II.
• Scheduled for elective LC under general anesthesia.

Exclusion Criteria:

• Anticipated difficult airway.
• Renal dysfunction.
• Hiatus hernia.
• Obesity.
• Pregnancy.
• Patients taking rate-controlling medications, steroids, opioids, or regular antacids.

The data will be available upon a reasonable request from the corresponding author after the end of study for one year.
